Habitat Use Of Sympatrically Nesting Fish Crows And American Crows, John Tanacredi Ph.D., Brook Lauro Nov 2003

Habitat Use Of Sympatrically Nesting Fish Crows And American Crows, John Tanacredi Ph.D., Brook Lauro

Faculty Works: CERCOM

We examined habitat use of sympatric Fish Crows (Corvus ossifragus) and American Crows (C. brachyrhynchos) nesting in the vicinity of waterbird breeding locations at the Rockaway Peninsula, New York City. Fish Crows nested significantly more often at natural habitats, including coastal dunes and salt marsh islands; American Crows nested significantly more often at residential and recreational areas. In regard to potential foraging areas, Fish Crows nested closer to waterbird colonies and to the water's edge while American Crows nested closer to a garbage source and to lawns. Fish Crows nested significantly more often in deciduous trees that were native ...


Water Quality Characterization And Mathematical Modeling Of Dissolved Oxygen In The East And West Ponds, Jamaica Bay Wildlife Refuge, John Tanacredi Ph.D., D Roy, Krishnanand Maillacheruvu Jan 2003

Water Quality Characterization And Mathematical Modeling Of Dissolved Oxygen In The East And West Ponds, Jamaica Bay Wildlife Refuge, John Tanacredi Ph.D., D Roy, Krishnanand Maillacheruvu

Faculty Works: CERCOM

The current study was undertaken to characterize the East and West Ponds and develop a mathematical model of the effects of nutrient and BOD loading on dissolved oxygen (DO) concentrations in these ponds. The model predicted that both ponds will recover adequately given the average expected range of nutrient and BOD loading due to waste from surface runoff and migratory birds. The predicted dissolved oxygen levels in both ponds were greater than 5.0 mg/L, and were supported by DO levels in the field which were typically above 5.0 mg/L during the period of this study. The ...
